Abstract:
Objective To investigate the clinical values and influencing factors of1H magnetic resonance spectroscopy(1H-MRS) in breast tumors.Methods Thirty-eight patients with breast tumors confirmed pathologically,including 20 cases of breast cancers and 18 cases of benign tumors examined by dynamic contrast-enhanced MRI and1H-MRS were studied retrospectively in comparison with pathology.The value of1H-MRS in detecting breast cancers was evaluated.Results On1H-MRS,11 breast cancers had increased choline peaks and 3 benign tumors presented increased choline peaks.The sensitivity,specificity and accuracy were 55.0%,83.3%and 68.4% respectively by using choline peak to detect breast cancers.Conclusion 1H-MRS has high diagnostic specificity for breast cancer.The low sensitivity of Choline to be detected rate in breast cancer is mainly dues to the lesions and technique factors.
